  • Information
    of the cases the maximum potential of protection of the gas detection system is not completely used or it might even come to dangerous situations when following this rule of thumb But we have to look into the properties of gases and vapours first To classify gases and vapours as lighter or heavier than air derives from the specific weight of the pure components Hydrogen methane and ammonia are mainly lighter than air All other components especially higher hydrocarbons are generally heavier than air The extension mechanisms derived from the rule of thumb mentioned above are only valid for undiluted components this means a gas concentration of 100 Vol supposed The use of gas detection systems serves for monitoring of undesired components at very low concentrations On the field of explosion protection the ranges of concentrations are below 5 v v whereas the ranges for toxic gases are in ppm and much lower There is no real difference in specific weight between gas mixtures with such low concentrations and ambient air Therefore their extension does not depend on the up or down draft of the gas but on other streaming influences such as wind or thermal lift A mixture of gas and air is not split into its fractions as wrongly supposed sometimes in case a mixture has already taken place Fig 1 This effect known for example from water oil mixtures does not appear on gases Fig 1 Muxture of gases The general situation is shown in Fig 2 Pure gas which is lighter than air emerges out of a leakage into the environment For the first instance the updraft prevails and the gas cloud rises By means of swirling and diffusion the gas is mixed with air As the up draft is more and more reduced the stream prevails and carries the gas with it In the described situation the gas detection unit installed in position A as per rule of thumb would not monitor the gas release or it would react too late In this case it would be much better to install the device in position B in case in combination with lower alarm levels to take the higher dilution into consideration If the potential sources of release could be further narrowed down the sensor element should alternatively be installed near to the source position C Fig 2 Example for the extention of a gas cloud Case 1 Rule of Thumb is a bad solution Situation Inside a big labour at a working place it is worked with hydrogen which is taken from a pressure gas bottle Leakages of the bottle or of the tubes should be monitored with a gas detection system Rule of Thumb The transmitter should be placed near the ceiling Better solution The transmitter is placed centrally only slightly above the working place Reason With a leakage pure hydrogen emerges and rises first At the same time the hydrogen is mixed with the ambient air With that up draft and concentration decrease
